ATTACHMENT FOR EXPLOSIVE-ENGiNES.

SPECIFICATION forming part of Letters ?atent No. 782,502, dated February 14, 1905.

Application filed February 15, 1904. Serial No. 193,621.

To aZZ whon'z, zit may concern:

Be it known that I, WILLIAM B. HAYDEN, a citizen of the United States, residing at New York city, in the county of New York and State of New York, have invented new and useful Improvements in Attachments for Explosive-Engines, of which the following is a specification.

This invention relates to attachments for explosive-engines of the class in which is employed an electrical sparking device for the explosive mixture.

Primarily the invention resides in a connecting means between the generator and the engine, and aims particularly to obtain an equal regularity of the speed of the generator-shaft, as Well as obtaining a steady and continuous rotary motion of the generatorshaft, whether the power-transmitting means for said shaft be a reciprocating or a rotary one, said means being further adapted to prevent sudden shocks to the generator and also enabling the storing up of suflicient power so that the generator can be operated in advance of its operation by the engine, as well as obtaining the operation of the generator in one direction whether the engine is reversed or running ahead.

The invention further aims to provide means for automatically throwing out of operation the generator when the engine is racing and to further provide means to permit of operating the generator manually, so that the generator can be operated in advance of the engine to obtain sufficient electrical energy to form a spark. so as to ignite the explosive or combustible mixture at the proper moment to prevent premature explosion and the kicking back of the engine when initially starting.

The invention further aims to provide new and novel attachments for obtaining the objects hereinbefore set forth and which shall be simple in construction, strong, durable, efficient in use and operation, and comparatively inexpensive to set up.

With the foregoing and other objects in view the invention consists in the novel combination and arrangement of parts hereinafter more specifically described, illustrated in the l bearing-stud l1 and shaft 9.

accompanying drawings, and particularly pointed out in the claims hereunto appended.

In describing the invention in detail reference is had to the accompanying drawings, forming a part of this specification, wherein like reference characters denote corresponding parts throughout the several views, in which Figure 1 is a top plan view of the engine with the attachments applied thereto. Fig. 2 is a side elevation of a portion of the attachments, showing a means for manually operating the generator, at part of the coupling device, and one form of power-transmitting means. between the coupling and the engine. Fig. 3 is a sectional elevation of the yielding coupling device. Fig. 1 illustrates a modified form of power-transmitting means between the engineand the coupling. Fig. 5 is a sectional detail elevation of one form of a governing device, and Fig. 6 is a sectional detail elevation of one form of a band-brake.

Referring to the drawings by reference characters, 1 denotes an electrical generator; 2, its shaft; 3, a governing device mounted on one end thereof, and at a pinion mounted on the other end of the generator-shaft 2.

The reference character 5 denotes the engine, 6 the engine-shaft, and 7 8 sparking-circuit wire connections between the generator and the engine.

The yielding coupling device between the generator and the engine consists of a shaft 9, having a socket 10 formed in one end thereof, and into said socket extends a bearingstud 11, upon which is fixed, as at 12, a gear 13. The gear 13 is connected to the shaft 9 through the medium of a coil-spring 14, surrounding a portion of the shaft 9 and the hub of the gear 13. One end of the spring 1a is connected, as at 15, to the gear 13, and the other end is attached, as at 16, to the shaft 9. Inter-posed between the pinion t (as well as meshing therewith) and the gear 13 (as well as meshing therewith) is a train of multiplying-gearing 17. The pinion 4, gear 13, and gearing 17 may be of any suitable form or construction. and the gearing 17 may be supported in any suitable manner, as well as the Fixed upon the shaft 9 is a toothed wheel 18, which can be manually operated, so as to rotate the shaft 9. Said wheel 18 is manually operated through the medium of a hand-lever 19, loosely mounted upon the shaft 9 and which carries a springactuated lever-and-pawl connection 20. It will be evident that when the lever-and-pawl connection 20 is normally operated the pawl of said connection will engage in the teeth of the wheel 18, and then by oscillating the lever 19, which carries the lever-and-pawl connection 20 therewith, motion will be imparted to the wheel 18, which in turn will operate the shaft 9, winding up or increasing the tension of the spring 1 1, the latter in turn rotating the gear 13, the latter imparting movement to the gearing 17, which in turn will rotate the pinion 4, thereby imparting motion to the generator-shaft 2.

In Fig. 2 of the drawings is shown a reciprocating power-transmitting means between the engine-shaft and the shaft 9, and said means comprises a hanger 21, loosely mounted upon the shaft 9. Said hanger 21 at its lower end is substantially yoke-shaped, as at 22, for partly surrounding the toothed wheel 18, and said yoke-shaped portion 22 of the hanger 21 carries a dog or pawl 23, which is supported therein through the medium of the pin 24:. The pawl or dog 23 is adapted to engage in the teeth of the wheel 18 for imparting motion thereto. The hanger 21 is adapt ed to be oscillated, so that such action of the pawl 23 as just stated will take place. The oscillations of the hanger 21 are obtained through the medium of a reciprocating rod 25, connected at one end to an eccentric 26, mounted on the engine-shaft 6, and at its other end to a wrist-pin 27, secured to the hanger 21. From the construction just set forth it is evident that when the engine is operated the rod 25 will be reciprocated through the medium of the eccentric 26 and oscillate the hanger 21, which will carry the pawl 23 therewith, so that said pawl 23 will engage in the teeth of the wheel 18 and rotate the same in one direction, thereby imparting a rotary movement to the shaft 9, and said movement of the shaft 9 will transmit motion in the manner as hereinbefore set forth to the generator-shaft 2.

The means for discontinuing the operation of the generator when the engine is racing comprises an automatically-movable releasing-arm 28, which is adapted to be slid in the path of the pawl 23 and engage said pawl 23, so as to cause the same to ride over and not engage in the teeth of the wheel 18, and consequently the motion imparted to the wheel 18 through the medium of the pawl 23 will be discontinued. For moving the pawl 23 so as to ride over the teeth of the wheel 18 the pawl 23 is provided with a protuberance 29, adapted to be engaged by said arm 28, thereby rocking the pawl 23 to such a position as to cause it to ride over the teeth of the wheel 18. The arm 28 is slid into the path of the pawl 23 through the medium of a rock-shaft 30, rocked by means of an actuating-arm 31, carried by the governor 3,when the speed of the generator exceeds a certain point or when the engine is racing. The action of the governor 3 under the conditions just set forth is such as to cause the actuating-arm 31 to rock the shaft 30 and slide the arm 28 in the path of the protuberance 29 of the pawl 23.

In Fig. 2 is shown a means for preventing back rotation of the toothed wheel 18, and said means consists of a pawl 32, mounted upon the standard The pawl 32 also acts in conjunction with a suitable braking means 34: for the generator-shaft 2. In this particular it will be stated that when the shaft 9 is operated the tension of the spring 14 will be increased, and if the engine is stopped the operation of the generator will be continued for a certain length of time, in view of the energy stored in the spring 1 1; but it has been found advantageous that upon the stopping of the engine it is well to stop the operation of the generator-shaft, so as to store up the energy in the spring 14, and this operation is obtained by means of any suitable braking device, as indicated by the reference character 31, operated by the brake-lever 3 1. \Yhen the brake is applied to the generator-shaft, back rotation of the toothed wheel 18 is prevented through the medium of the pawl 32. When the brake is released before the engine is started, it is evident that sufiicient energy is stored in the spring 141 so that the generator will be operated in advance of the engine. It may be well to state that the engine may be started in any suitable manner.

In Fig. at of the drawings is shown a modified arrangement for connecting the shaft 9 with the engine, and this modified arrangement is termed a rotary one and consists of the sprocketw heel 35,carried by the en gi neshaft, and asproclret-wheel 36,carried by but loose upon the shaft 9. The wheels 35 and 36 are connected by a chain 37. The wheel 36 and shaft 9 are provided with a pawl-audratchet mechanism 38 for driving said shaft. Back rotation, as in the other structure, is prevented through the medium of the pawl 32 engaging the wheel 18.

In Fig. 5 is shown one form of a governing device and which consists of a disk wheel 40, secured to the shaft 2 and revolving therewith, friction-levers 4C1, pivoted to the wheel 10, as at 12, and revolving with said wheel +10, pulling-springs 43, connected at one end to the wheel 10 and at their other ends to the levers 411 for retaining said levers 11 normally against the stops 491, and a band-wheel 4-5, loosely mounted upon the shaft 2 and inclosing the levers 41. The band-wheel 15 carries 30, as at 46.

to retain the arm 31 against a stop 48. operation of the governing device such that when the generator reaches its maximum speed the levers 4L1 engage the band-wheel 45, causing the same to travel therewith and operating the rod 31, thereby actuating shaft in a manner as hereinbefore referred to.

In Fig. 6 of the drawings the form of bandbrake illustrated consists of a disk 49, fixed to the shaft 2 and inclosed by a band 34. The band 34 is fixed at one end. as at 50, and connected at its other end, as at 51, to the brakelever 34:. i

The interposition of the gearing 17 between the spring 14 and the generator is for the purpose of obtaining the proper speed of the gen erator for a low-speed or other form of engine, as well as obtaining the necessary speed of the generator for initially starting the same by the manual operation hereinbefore set forth without much effort on the part of the operator when oscillating the lever 19, for the reason that buta few oscillations of the lever 19 are all that is needed when it is necessary to initially start the generator or start the engine.

By the employment of the yielding spring connection 14 in the manner as set forth it has been found that the said spring connection acts to ward off sudden shocks to the generator and also obtains a steady and continuous motion, as well as equal regularity in speed of the generator-shaft. The spring connection, together with the other parts of the coupling means between the generator and the engine, will also cause the operation of the generator in but one direction whether the engine is reversed or running ahead.

The means hereinbefore set forth for throwing the generator out of operation when the engine is racing also acts as a means to throw the generator out of operation when the engine is going at such a rate of speed as would be injurious to the generator. In this particular the governing device will act upon the arm 28 in the manner as hereinbefore set forth, consequently disconnecting the power-transmitting meansfrom the engine to the shaft 9.

It is thought the many advantages of the foregoinginvention can be readily understood from the description thereof, taken in connection with the accompanying drawings, and it will furthermore be evident that changes, variations, and modifications can be resorted to without departing from the spirit of the invention or sacrificing any of its advantages,

and 1 therefore do not wish to restrict myself to the details of construction hereinbefore described and as set forth in the annexed drawings, but reserve the right to make such changes, variations, and modifications as come proper for the adaptation of the invention to any usages for which it may be employed, said changes, variations, and modifications to The come properly within the scope of the protection prayed.
